Forensic Bird-Strike Identification Techniques Used In An Accident Investigation At Wiley Post Airport, Oklahoma, 2008, Carla J. Dove, Nor Faridah Dahlan, Marcy Heacker

Human–Wildlife Interactions

On March 4, 2008, a Cessna Citation 1 (Model 500) crashed in a wooded area near Wiley Post Airport, Oklahoma, killing all 5 people on board. This paper describes the detailed forensic methods and expertise used by the Smithsonian Institution’s Feather Identification Lab to identify the bird that caused this bird-strike incident. We used standard methods of whole-feather analysis, microscopic examination, and DNA barcoding in this case to identify American white pelican (Pelecanus erythrorhynchos) as the bird species involved in this fatal crash. We also report the importance of proper field investigation and evidence collection for accurate results, …

Using Wedelia As Ground Cover On Tropical Airports To Reduce Bird Activity, Michael A. Linnell, Michael R. Conover, Tim J. Ohashi

Human–Wildlife Interactions

aircraft collisions (i.e., bird strikes) are a major problem at airports worldwide, often because birds are attracted to airfields to feed on seeds, insects, or rodents that abound in the grassy areas near runways and taxiways. We compared an alternative ground cover, wedelia (Wedelia trilobata), to existing vegetation (control plots) on the airfield at Lihue Airport, Kauai, Hawaii, to determine if bird populations on the airport could be reduced by eliminating their forage base. We studied wedalia because it is a low-growing plant that did not need mowing, was easily established in plots, and out-competed other plants, resulting …

In The News, Joe N. Caudell

Human–Wildlife Interactions

Bird dogs of a different feather-- A report from the website of 10 Connect News of Tampa, Florida, reported that a bird-chasing border collie, a breed of dog, is being used to harass birds at airports. The dog is just 1 part of MacDill Airforce Base’s safety management program to reduce damage at airfields.

Survival And Productivity Of A Low-Density Black Bear Population In Rocky Mountain National Park, Colorado, Roger A. Baldwin, Louis C. Bender

Human–Wildlife Interactions

Rocky Mountain National Park (RMNP) has supported a small black bear (Ursus americanus) population of low productivity. Increased visitor use of the park and development around its periphery could lead to a reduction in population viability of RMNP’s bear population or could increase the potential for human–bear conflict. Therefore, we investigated contemporary survival and productivity parameters for RMNP’s black bear population from 2003 to 2006 and compared these values to historic levels (1984–1991) and population means throughout the western United States to clarify the current status of RMNP’s bear population. The contemporary black bear population showed signs of …

Molt Migration By Giant Canada Geese In Eastern South Dakota, Charles D. Dieter, Bobby J. Anderson

Human–Wildlife Interactions

We captured giant Canada geese (Branta canadensis maxima) in 7 counties in eastern South Dakota during the summer molting period, 2000–2003. We attached very high frequency (VHF) transmitters to 150 adult female geese with brood patches, and leg bands to 3,839 geese. We documented molt migrations using VHF telemetry and indirect band recovery at locations north of South Dakota. Telemetry of radio-collared female geese during the breeding season indicated that 56% of nonbreeders, 81% of unsuccessful breeders, and 19% of successful female breeders embarked on a molt migration. Five of 34 geese that underwent molt migrations moved to …

Developing Bird-Strike Risk Assessment Models For Open-Water Restorations, Justin D. Hart, Alison Colyer, John R. Allan

Human–Wildlife Interactions

Mineral extraction sites that are restored to open water can increase bird-strike risk if they are planned near airports. This can generate conflict between the minerals industry and safeguarding authorities. To help resolve this potential conflict, it would be useful to predict how new restorations affect local water-bird populations so that mineral deposits can be exploited and restored in safeguarded zones without compromising flight safety. Bird abundances and movements at new restorations can be estimated with statistical models that use the environmental characteristics of restoration schemes as predictor variables. These models can improve guidance in safeguarding, provided that they comprise …

Management Of Bayberry In Relation To Tree-Swallow Strikes At John F. Kennedy International Airport, New York, Glen E. Bernhardt, Zachary J. Paton, Lisa A. Kutschbach-Brohl, Richard A. Dolbeer

Human–Wildlife Interactions

Tree swallows (Tachycineta bicolor) have been a periodic bird-strike problem at John F. Kennedy International Airport (JFKIA), New York, New York, causing runway closures, flight delays, and damage to aircraft following the ingestion of bird flocks into engines. We examined 65 tree swallows collected at JFKIA in October 2001 to determine food sources that were attracting the birds to the airport. Digestive tracts of all 65 specimens contained northern bayberry fruits (Myrica pensylvanica), averaging 15.6 fruits per bird or 3.4% of the bird’s body mass in specimens where the entire tract was dissected. Bayberry fruits are …

Coexisting With Cougars: Public Perceptions, Attitudes, And Awareness Of Cougars On The Urban-Rural Fringe Of Calgary, Alberta, Canada, Clarisse Thornton, Michael S. Quinn

Human–Wildlife Interactions

Interactions between humans and cougars (Puma concolor) have been steadily increasing over the past 20 years largely due to human encroachment into cougar habitat and an increase in the human population. We determined the attitudes, knowledge, and perceptions toward cougars by residents in the urban-rural fringe of Calgary, Alberta, Canada, an area populated by both cougars and humans. We sent a survey to a stratified, random sample of 1,508 residents. Survey analysis included a potential for conflict index (PCI) to help provide quantitative direction for future cougar management. We analyzed and tested for differences among 7 variables: livestock …

Setting Research Priorities At Wildlife Services’ National Wildlife Research Center, Richard L. Bruggers

Human–Wildlife Interactions

As director of the Wildlife Services’ National Wildlife Research Center (NWRC), I frequently have been asked how the NWRC determines, prioritizes, and implements its research agenda. To answer this question, I will start by giving both a historical overview and an update of the NWRC. The mission of the NWRC is to provide science-based tools and information to resolve human–wildlife conflicts.

The Cost Of Fear, Michael R. Conover

Human–Wildlife Interactions

I hope that someday, we will be able to quantify the lost-opportunity costs associated with human–wildlife conflicts. Until that day, I hope that wildlife biologists and other people who help to make air travel safer have the satisfaction of knowing that what they do is important. They help people live better, safer, and more enjoyable lives. I cannot think of a higher calling than that. In tribute to them, I am pleased that this issue of Human–Wildlife Conflicts features several articles on the topic of bird–aircraft collisions. These include studies examining techniques that can reduce the danger of bird–aircraft collisions …

Safety Management Systems: How Useful Will The Faa National Wildlife Strike Database Be?, Richard A. Dolbeer, Sandra E. Wright

Human–Wildlife Interactions

The National Wildlife Strike Database for Civil Aviation in the United States became operational in 1995 with the initiation of data entry of all strike reports beginning in 1990. The database contained 82,057 reported strikes from 1990 to 2007. About 9,800 of these strike reports noted damage to the aircraft, of which 2,700 indicated the damage was substantial. The database has proven to be a useful source of objective information on the extent and nature of wildlife strikes for personnel at individual airports and for researchers and regulatory agencies at the national level. With the impending requirement for airports in …

Observations Of Neck-Collared Canada Geese Near John F. Kennedy International Airport, New York, Thomas W. Seamans, Scott E. Clemons, Allen L. Gosser

Human–Wildlife Interactions

Canada geese (Branta canadensis) often cause significant damage when they strike aircraft. They are responsible for a reported minimum of $2.6 million in damage per year to civil aviation in the United States. Knowledge of goose movements in relation to airports would allow wildlife managers to allocate time and funds to manage those populations that pose the greatest threat to aircraft. We placed alpha-numeric neck collars on 300 Canada geese within 8 km of both John F. Kennedy International Airport (JFKIA) and LaGuardia Airport in New York, New York. We conducted weekly observations for 2 years within a …

Birds And Aircraft—Fighting For Airspace In Ever More Crowded Skies, Richard A. Dolbeer

Human–Wildlife Interactions

This special issue of Human–Wildlife Conflicts (HWC) was conceived 1 year ago by Bird Strike Committee–USA (BSC–USA) and the Berryman Institute. Our premise was that the collision of aircraft with birds (bird strikes) and other wildlife is a growing problem about which the general public and most scientists and wildlife biologist know very little. Furthermore, although considerable work has been done to mitigate the risks caused by bird strikes, there have been few peer-reviewed publications of these research and management efforts. Thus, our 2 goals were to (1) educate the broad readership of HWC about the growing safety and economic …

Role Of Near-Miss Bird Strikes In Assessing Hazards, Matthew W. Klope, Robert C. Beason, Timothy J. Nohara, Michael J. Begier

Human–Wildlife Interactions

Management of problem wildlife within the airfield environment is a difficult job. Today’s Bird–Animal Aircraft Strike Hazard (BASH) program managers require as much information as possible to accomplish their tasks. Bird censuses and actual bird-strike events in and around the air operations area are used to make airfield management decisions and to assess the risk of bird hazards to aircraft. Both types of information are sampled rather sparsely. Avian radar is now being used as a new tool to provide continuous sampling of bird activity that significantly supplements visual censuses. The measure of risk used today is commonly expressed as …

Personal And Corporate Liability In The Aftermath Of Bird Strikes: A Costly Consideration, Larry A. Dale

Human–Wildlife Interactions

This paper details liability issues inherent in bird–aircraft collisions (bird-strike) incidents at airports and discusses how airport managers and operators must strive to conduct accurate assessments and develop and implement an effective wildlife management plan. Such efforts are mandated by Federal Aviation Administration (FAA) regulations, and failure to follow them may result in loss of human life and property, as well as large financial penalties for managers and operators and adverse media attention and public criticism for the airport authority.

Burrowing Owl And Other Migratory Bird Mitigation For A Runway Construction Project At Edwards Afb, Amber L. Hoen, Mark Hagan, Mark Bratton

Human–Wildlife Interactions

Edwards Air Force Base (AFB) scheduled the construction of a runway in the spring of 2007. The runway would be in an area that contained migratory birds and their habitat. The construction project would be near Edwards AFB main runway and had the potential not only to impact species protected under the Migratory Bird Treaty Act (MBTA), including the burrowing owl (Athene cunicularia), but also to increase bird and wildlife–aircraft strike hazards in the active flightline areas. To discourage nesting in the project area, reduce the potential for bird and wildlife–aircraft strikes, and maintain compliance with federal environmental …

A Tribute To Richard A. Dolbeer: Scientist, Innovator, Manager, And Mentor, Bradley F. Blackwell, Travis L. Devault

Human–Wildlife Interactions

Richard A. Dolbeer retired in September 2008 from the U.S. Department of Agriculture, Wildlife Services (WS) program. Over the last 30 years, his research has encompassed the areas of population dynamics of pest species, economic assessment of losses, development of practical management techniques for resolving human–wildlife conflicts, and integrated pest management programs in the United States and abroad (Africa, Asia, Latin America). Most notably, he is one of a few individuals who recognized, early on, the cost in lives and property due to wildlife collisions with aircraft and that much of that cost is avoidable through the application of findings …

A Decade Of U.S. Air Force Bat Strikes, Suzanne C. Peurach, Carla J. Dove, Laura Stepko

Human–Wildlife Interactions

From 1997 through 2007, 821 bat strikes were reported to the U.S. Air Force (USAF) Safety Center by aircraft personnel or ground crew and sent to the National Museum of Natural History, Smithsonian Institution, for identification. Many samples were identified by macroscopic and or microscopic comparisons with bat specimens housed in the museum and augmented during the last 2 years by DNA analysis. Bat remains from USAF strikes during this period were received at the museum from 40 states in the United States and from 20 countries. We confirmed that 46% of the strikes were caused by bats, but we …

Suspending Vulture Effigies From Roosts To Reduce Bird Strikes, Steven A. Ball

Human–Wildlife Interactions

I observed very few vultures over the airfield after deploying the effigies, and vultures were completely absent most days. Hanging vulture effigies seemed to be effective in pushing the vultures farther away by denying them their observation point looking over the Coastal Plain near the airfield. This meant that their forage center point had been relocated far enough from the airfield that few individuals extended their range as far as the airport.

Bird Strikes And The Courts: The Antonov Case, Valter Battistoni

2009 Bird Strike North America Conference

At the 4th Bird Strike Committee USA – Canada Joint Meeting (2002), I presented a paper more or less with the same title as this one, called “The Genoa Case”. I thought it would have been useful for such an international audience to know the outcome, at first degree level, of the first Italian civil lawsuit for damage compensation following a multiple bird strike with ingestion that occurred at Genoa airport in 1989.

Later on, in 2004, I was entrusted by ENAC (Italian CAA) to support the Agency’s defence as a technical consultant in a new lawsuit regarding another multiple …

Biofuels: Cultivating Energy, not Invasive Species, approved by ISAC on August 11, 2009

ISSUE

To provide alternatives to petroleum-based energy, the United States government has mandated a greater proportion of plant-based biofuels be integrated into its energy portfolio. However, certain plant species being proposed for biofuel production in the United States are invasive species or are likely to escape cultivation and become invasive. United States Executive Order (EO) 131121 defines invasive species as “alien [non-native] species whose introduction does or is likely to cause economic or environmental harm or harm to human health” and states: “Each Federal agency whose actions …

Lead Detection In Water: Using Hydroxyapatite And Atomic Absorption, Nicolas Cantarero

Department of Environmental Studies: Undergraduate Student Theses

Hydroxyapatite is a mineral that is very inexpensive, easily made, and binds well to lead. In this procedure its application will be paired with Flame Atomic Absorption Spectroscopy (Flame AA) to detect lead concentrations in water to ppb levels. While ppb concentrations of lead are too dilute to produce a response from the Flame AA by using Hydroxyapatite to concentrate lead molecules from a larger volume and dissolving the Hydroxyapatite into a smaller volume it may be able to produce a response. The method could provide an inexpensive, efficient, and accurate way to detect lead concentrations to the ppb level …

The Human Side Of Invasive Species, Ben C. West

Human–Wildlife Interactions

Feral hogs (Sus scrofa) are one of the most visible, troublesome, and interesting invasive species in North America. They have existed in North America probably since 1493 when Christopher Columbus purportedly released some hogs in the West Indies. Since then, hogs have spread across the continent and increased substantially in number. Today, feral hogs are both numerous and widespread throughout North America (Gipson et al. 1998, Adkins and Harveson 2007, Fogarty 2007, Mersinger and Silvy 2007), and published estimates suggested a U.S. population of between 1 and 2 million feral hogs (Mayer and Brisbin 1991).
